Summary:
- The study found that nearly half of the world's glaciers are already doomed to melt, even if we stop all future global warming.
- This is because the glaciers have already reached a point of no return, where they will continue to shrink and disappear over the next few decades.
- The melting of these glaciers will lead to a significant rise in sea levels, which could have devastating effects on coastal communities and ecosystems around the world.
